JOHN J. QUACKENBUSH, OF- LAKEVIEW, NEIV JERSEY.

SHUTTER-FASTENER.

SPECIFICATION forming part of Letters Patent In 0. 768,195, dated August 23, 1904.

Application filed March 25, 1904.

To all whom it may concern.-

Be it known that I, JOHN J. QUAcxENBUsH, a citizen of the United States,residing in Lakeview, in the county of Passaic and State of New Jersey, haveinvented certain new and useful Improvements in Burglar-Proof Shutter-Fasteners; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to means for securing blinds or the like in closed position; and it has for its principal object to so constructa hasp that it will confuse and deceive one attempting to surreptitiously manipulate it without being able to visually determine its construction and operation.

My improved locking device is shown in the drawings as applied to surfaces which when in the position for locking stand in substantially the same plane; but it will be understood that said locking device is adapted to be attached tosurfaces which when in the position referred to stand at right angles-as in the I case of a blind or the like and its casing.

The invention will be found fully illustrated in the accompanying drawings, wherein- Figure 1 shows one form of' the invention with the parts arranged inlocking position. Fig. 2 shows the same form of the invention as is shown in Fig. 1, with the locking-plate in unlocking position and the hinged leaf thrown back. Fig. 3 is a view in side elevation of what-is shown in Fig. 1. Fig. 4 shows another form of the invention with the parts arranged in looking position. Fig. 5 shows that form of the invention which is illustrated in Fig. 4:, with the locking-plate arranged in the unlocking position, the parts being otherwise arranged, as in Fig. 4; and Fig. 6 shows that form of the invention illustrated in Fig. 4 with the locking-plate in unlocking position andthe hinged leaf of the hasp thrown back.

An ordinary hasp is shown in all the figures Serial No. 199,977. (No model.)

of the drawings, where a is its fixed leaf, and 6 its hinged leaf, pivoted together at c in the usual manner.

In the form of the invention shown in Figs.

1, 2, and 3 a locking-plate k is hinged on a in from one side thereof and arranged concentric with the pivot Z. A recess 1" is formed in the side of the locking-plate Z5 in such disposition that when the plate is turned sufiiciently said recess will approximately coincide with the end of slot 0. Such recess,therefore, only permits the parts to'come into'the position shown in Fig. 1 upon the lockingplate being made to first assume this position.

In that form of the invention shown in Figs. 4, 5, and 6 the locking-plate sis pivoted on the hinged leaf 6 of the hasp at ton an axis which extends parallel with. the axis of the hinge c of the hasp. The locking-plate is formed in this instance with a longitudinal slot at, extending in from its free end. The securing-piece comprises a plate 4) and a turnbutton w, the same as the corresponding parts so far as they extend, with each other, as will be seen upon perusing any of the figures of the drawings. To onejattempting to manipulate the device to unlock it without being able to observe its construction, as in the case of a burglar who has removed only enough of the slats of a blind to admit one hand, this formation of the parts will afford confusion and materially embarrass his operations. To further the deception in the case of the form of the invention shown in Fig. 1, the side of the plate is opposite tothe recess 0* may have a corresponding recess r, the outline of the hinged leaf of the hasp being at this point correspondingly formed.

In those forms of the invention shown in Figs. 1 to 6, inclusive, the securing of the parts together and the avoiding of looseness are accomplished by the use of a turn-button, such as that shown, which can be screwed down tight against the parts with which it directly engages, as shown in Fig. 3.

In order that the hinged leaf of the hasp may be secured down permanently, as when the blind is to remain closed for long periods, I provide the hinged leaf of the hasp near the end with a hole w and the locking-plate with a coinciding hole 1 (in all forms of the invention except that shown in Figs. 4, 5, and 6, where the slot 10 will coincide with the hole m.) These holes are adapted to receive a securing-screw or the like.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination, with a hinged hasp, of a turn-button, a suitable mounting for the turnbutton, and a locking-plate pivotally arranged on the hinged leaf of the hasp, said hinged leaf of the hasp and the locking-plate having substantially corresponding slots and said locking-plate being movable to bring its slot into coincidence with that of the hinged leal so as to admit the turn-button, substantially as described.

In testimony that I claim the foregoing l have hereunto set my hand this 24th day 01 March, 1904.
